Save your photos to a secure place, create memos about meetings for your team and access them in shared folders on the go – and be sure that no one can read your files besides you and those who you share with. Tresorit uses built-in end-to-end encryption with zero-knowledge standards to guarantee the highest level of security. All your files are encrypted on your device before they are uploaded to the cloud, which means no one else can read them besides you, no hackers, no authorities, not even Tresorit’s IT admins.

Features: • Create shared folders (tresors) with your friends or colleagues, access their contents securely on any iOS device • Backup your photos in a secure place with end-to-end encrypted camera upload • Keep control of your files by managing permissions • Share files securely even with those without an account: send links instead of risky attachments • Create favorite tresors, access and edit your files even when you are offline • Protect your account with 2-factor authentication and app passcode to ensure no one has access to your tresors - even if someone gains access to your phone • Say no for tracking: Tresorit for iOS accesses the least it has to. No location tracking, no access to your contacts • Tresorit for iOS features the same end-to-end encryption and security as the desktop apps • Make the most out of Tresorit by adding the desktop client as well (sync between devices, locations, access your files from all devices) What do others say about Tresorit? “One of the Best Cloud Storage Services that Protect Your Privacy” – LifeHacker “There are several services that offer secure storage in the cloud, but Tresorit is definitely one of the best” – PC Advisor
